In an exclusive clip from Tuesday's Real Housewives of Beverly Hills, Rinna takes issue with Edwards' behavior during a dinner party Erika Girardi is hosting to introduce the ladies to her husband Tom.
Edwards, 51, dominates the conversation (with talk of foreplay, among other things), with others trying to break in to change the topic. Rinna, 52, isn't having it.

"You know you talk a lot! You have to let people get in a little bit because you talk a lot," Rinna tell Edwards.
She further explains her feelings to the camera.
"Kathryn is talking so much and she's loud and she's aggressive," Rinna tells the camera. "I'd like to muzzle Kathryn at this point. Tape would work too. Like, duct tape."
For her part, Edwards says she's "very passionate" and is only trying to try to demonstrate to Girardi why the pair should be friends. Is it working? Judging from the clip, it's going to be a long road.
The Real Housewives of Beverly Hills airs Tuesdays (9 p.m. ET) on Bravo.
